TSR is a compressor and archiver for macOS, Windows and Linux. This is the test version: it is a beta and may have defects, so always keep the originals of the files you compress. The archives you create open forever, even after the beta ends.

The programs are not yet signed with Apple and Microsoft certificates: on first launch the system warns you, and how to open them is explained below. The fingerprint of each package tells you whether you downloaded exactly these bytes.
Installing
macOS
Open the zip and move TSR.app to the Applications folder: from there the program updates itself (opened from Downloads it cannot, and it says so).
On first launch macOS warns that it cannot verify the app, because it is not yet signed with an Apple certificate: open System Settings → Privacy & Security and choose “Open Anyway”.
The command line is tsr: keep it in a folder of yours, for example ~/bin; the first time it is unblocked the same way.
Windows
Unzip it in a folder of yours, not in Program Files, so that the program updates itself, and start tsr-gui.exe.
On first launch SmartScreen warns you, because the program is not yet signed with a certificate: choose “More info” and then “Run anyway”.
The command line is tsr.exe.
Linux
Unpack the archive in a folder of yours (tar -xzf) and start tsr-gui; tsr is the command line.
The program updates itself. For servers there are also .deb and .rpm packages and container images: they come with the version for companies.
On first launch
TSR shows the terms of the beta channel: they must be accepted to compress. Opening, extracting and verifying archives always works, even without accepting them and after the beta ends.
Right after, it asks whether you want to send us crash reports and usage metrics. They stay off until you turn them on, never contain file names, paths or contents, and go to a server in Germany that does not keep IP addresses.
The texts, to read before downloading: beta channel terms · diagnostics privacy notice
Updates and the end of the beta
The program periodically checks for a new version, sending only its version and the operating system. Updates are signed, download in the background and install at the next restart, never during a job; the previous version stays, to go back.
By 31 January 2027 at the latest compression closes, and the program says so. Archives open and extract forever.
Checking what you downloaded
Every package has its SHA-256 fingerprint above, and all of them are in the file SHA256SUMS, which carries an eIDAS qualified timestamp of 27 September 2026 (Sectigo) and a second one from DigiCert. To check a package:
shasum -a 256 TSR-beta-0.10.2-macos-arm64.zipGet-FileHash TSR-beta-0.10.2-windows-x64.zipThe result must match the package’s fingerprint.
